# nix/devShell.nix — Dev shell that delegates setup to each package
#
# Each npm workspace package exposes passthru.packageJsonPath (e.g.
# "ui-tui/package.json"). This file collects them all and passes the
# list to mkNpmDevShellHook, which stamps all package.jsons at once,
# then runs a single `npm i --package-lock-only` if any changed and
# `npm ci` if the lockfile changed.
